Claims.

This invention relates to improvements in an automatically controlled valve, and more particularly to a simple device that automatically controls outside air or vapor supplied to the intake manifold of an internal combustion engine.

An object of this invention is to furnish an easily adjustable means for automatically regulating the amount of free air or vapor supplied to the combustible gas through the intake manifold of an internal combustion motor, without any additional carburetor adjustment.

Another object of this invention is to furnish an automatically controlled valve for supply air or vapor, the amount of vapor being increased 5 as the speed of the engine increases and reduced as the speed of the engine is reduced, taking care of the change in air supply necessary with the variation in engine speed.

With the above and other objects which will be apparent as the description proceeds, my invention consists of the following novel features and method of construction which are illustrated in the accompanying drawings and pointed out in the appended claims.

In the accompanying drawings,

Fig. 1 shows the device in its entirety attached a conventional type of internal combustion engine, supplying the vapor from the crank case, to illustrate the principle of the device.

Fig. 2 is a perspective rear View of the automatic control valve.

Fig. 3 is a front view of the automatic control valve.

Fig. 4 is a cross sectional View of valve showing the valve arrangement.

Fig. 5 is a fragmentary cross sectional rear view of the automatic control valve showing its detailed construction.

Referring to the drawings in detail where like characters of reference denote corresponding parts, character iii indicates an internal combustion engine having a fan ll actuated by belt l2 working off of the crank shaft it, there is an automatic control valve i l supported by a con- 5 ventional bracket 55, which is fastened thereto by screws at 24, and to the engine it by means of bolt [6, the tube ll, leading from the breather spout IS in the crank case of the engine and a tube l9, leading from the control valve it, to the vapor inlet 28, which is placed between the carburetor outlet 2i, and the intake manifold 22,

the control valve 14 consists of a housing 23, having holes 24 at its top for attaching bracket l5.

The front of the housing 23, has louvres 25 to permit the air to enter.

the control 1934, Serial No. 726,422 ((31. 137-139) There are brackets of housing 23, which 26 mounted on the inside support the ends of both tubes l? and i9, leaving a vertical opening 2?,

between the tubes.

There is a vane 28 having a right angular section 29 with a port 38, this vane 28 is hinged at its center or fulcrum 3i and normally hangs in a verti counterweights or both may be used as means of returning th tion.

There are radial slots 32 cal position but springs or a modified e vane to its normal posion the side of housing 23 to act as an indicator for vane 28.

In operation the automatic control valve 14 is mounted on the forward end of the engine immediately behind the fan location. In the drawings it an angular bracket 0 l l, or any other convenient is fastened at 24 to r support l5 bolted down onto the engine with bolt it, there is a tube l7 leading from either the breather spout [8 in the crank case of the e ngine, the radiator, or any control valve M has a vane 28 pivotally mounted having a flat section 29 at right angle to the vane 28 operating between H9 at 2?, the flat section the ends of tubes I! and 29 of the vane 28 has an aperture or port 39, and when the air from the fan i l is blown through the louvres 25 into the housing 23 of the control valve M, the vane 28 is forced backward swinging on its pivot 3| causing the port 36 in ister with the ends of the flat section 29 to regthe tubes ll and I9.

The operation of the pistons in the cylinders of engine it causes a suction,

drawing in the gaseous fumes through the intake manifold 22,

from the carburetor creates a suction in the or aperture 36 registers the end of the tubes 2! and in doing so also tube 19, when the port partially or fully with IT and 89 this suction is further proportionately imparted to the tube ll drawing the air or vap or to mix with the gases in the intake manifold 22.

The entire installation of this device can be made without any mechanical change or alteration in the construction of the internal combustion engine, whether used on automobile, aeroplane, or motorboat, a

trol the amount of air combustion chamber fold 22, depending on tacting the vane in obvious that the fast greater the velocity 0 nd will automatically conor vapor drawn into the through the intake manithe velocity of the air conthe control valve. It is er the engine is run the f air hitting the vane 28,

whether this air is produced by the fan ll operated by the crank shaft E3, or whether it is produced by the speed of the automobile, aeroplane, or motorboat. The more air hitting the vane 28 in the control valve 54 the wider it will open the port 31! and the more air or vapor will be drawn into the combustion chamber of the motor.

Having thus described claim and desire to secure the United States, is:

1. A valve comprising a housing having louvres in its front wall, a vane within said housing, and pivotally supported from the top wall thereof, inlet and outlet ducts having opposed open ends extending into said housing, and an angular projection on said vane interposed between the open duct ends and having a port adapted to my invention, what I by Letters Patent of register with the duct openings when said vane.

is swung on its pivot support from its normally depending position within said housing by pressure of air entering said louvres.

2. A valve, comprising a housing having a perforated front Wall, inlet and outlet ducts extending into said housing and having opposed ends disposed in closely spaced relation therein, a pivotally mounted vane, a projecting member carried by said vane, and having a port therein, said member being disposed between the open ends of said ducts and normally closing the same, said port in said projecting member being adapted to register with the open ends of said ducts when said vane is swung on its pivot support by pressure of air entering said perforations.

3. A valve of the class described, comprising a housing open at its rear side and having a perforated front wall, a movable vane disposed in rear of and parallel to said front wall, ducts entering said housing and having opposed open ends disposed in closely spaced relation, and a ported valve body carried by said vane and disposed between the open ends of said ducts, said vane being operable by the pressure of air entering the said perforations to move said valve body to register the port therein with the open ends of said ducts.

4. The valve as set forth in claim 3 wherein the said vane is pivotally suspended from the top wall of said housing and has a lateral projection adjacent its lower end engaged in an arcuate slot formed in a side wall of the housing to stabilize the operative movements of the vane.
